On The Necessity of Multiphysics Simulation Experiments in MEMS Teaching

Jinying Zhang, Wei-Jiang Xu, Xianmei Wu

Microelectromechanical system (MEMS) is an interdisciplinary research and education field. The multiphysics simulation can make the abstract theory on MEMS design concrete and improve the learning efficiency. A MEMS course design is presented in this paper. The content consists of fundamental…

Hierarchical large-scale elastic metamaterials for passive seismic wave mitigation

M. Miniaci, Nesrine Kherraz, Charles Croënne, Matteo Mazzotti, Maryam Morvaridi, Antonio S. Gliozzi, Miguel Onorato, Federico Bosia, Nicola Maria Pugno

Large scale elastic metamaterials have recently attracted increasing interest in the scientific community for their potential as passive isolation structures for seismic waves. In particular, so-called “seismic shields” have been proposed for the protection of large areas where other isolation…

18 - Optical Tamm States in Semiinfinite Layered Photonic Crystals

Abdellatif Akjouj, El Houssaine El Boudouti, L. Dobrzynski, Bahram Djafari-Rouhani, Gaëtan Lévêque

We investigate localized and resonant optical waves associated with a semiinfinite one-dimensional photonic crystal constructed by two different layers (1 and 2) and terminated with a cap layer. In this chapter, we present an analytic determination of the response function (Green's function)…

12 - Serial Loop Structures: Photonic Bandgaps, Confined, Cavity, and Surface Modes

El Houssaine El Boudouti, Bahram Djafari-Rouhani, Abdellatif Akjouj, L. Dobrzynski

In this chapter, we investigate the electromagnetic band structure, transmission, phase time, as well as confined and surface modes in a one-dimensional photonic structure made of loops pasted together with segments of finite length. In this serial loop structure, the loops and segments are…

10 - Photonic Demultiplexers Based on Fano and Induced Transparency Resonances

El Houssaine El Boudouti, Abdellatif Akjouj, Bahram Djafari-Rouhani, Abdelkrim Talbi, L. Dobrzynski

In this chapter, we give an analytical and experimental demonstration of the possibility to realize a simple photonic demultiplexer based on Fano and electromagnetically induced transparency resonances. The demultiplexer consists on a Y-shaped waveguide with an input line and two output lines. Each…

Equivalence between angular spectrum-based and multipole expansion-based formulas of the acoustic radiation force and torque

Zhixiong Gong, Michael Baudoin

Two main methods have been proposed to derive the acoustical radiation force and torque applied by an arbitrary acoustic field on a particle: The first one relies on the plane wave angular spectrum decomposition of the incident field (see Sapozhnikov and Bailey [J. Acoust. Soc. Am. 133, 661-676 (…

23 - Multilayered Structures Based One Dimensional Photonic Crystals for MEMS Applications

Cécile Ghouila-Houri, Abdelkrim Talbi, Abdellatif Akjouj, El Houssaine El Boudouti, Bahram Djafari-Rouhani, L. Dobrzynski

This chapter presents and discusses the modeling of multilayered structures based 1D photonic crystals for micro-electro-mechanical systems (MEMS) applications. We particularly report in this chapter a design for realizing a 1D photonic crystal cavity based on highly flexible thin elastomer that…

4 - Open loop examples

Housni Al Wahsh, L. Dobrzynski, Abdellatif Akjouj, El Houssaine El Boudouti

The simplest general robust zero is the middle of an open loop. When the middles of several free-end open loops of the same length are superposed, their antisymmetric eigenfunctions remain unperturbed and the final network has several degenerate states. The next three examples take into account…

5 - Closed loop examples

Housni Al Wahsh, L. Dobrzynski, Abdellatif Akjouj, El Houssaine El Boudouti

The specific properties of closed loop eigenfunctions deserve to be better understood. This chapter underlines that responses in closed loops differ from the responses in open loops. Within the following simple examples, constructed on closed loop robust zeros, many path states are found.A robust…

21 - Layered Photonic Crystals with Left-Handed Materials

Abdellatif Akjouj, El Houssaine El Boudouti, L. Dobrzynski, Bahram Djafari-Rouhani

We theoretically investigate the photonic band structure of layered photonic crystals composed of alternating layers of right- and left-handed materials (RHMs and LHMs). The dispersion curves are mainly studied by assuming that the dielectric permittivity and magnetic permeability are constant in…
